Hello everyone,

I’m looking to run CFX coupled with transient structural analysis on a Linux system. However, due to the absence of a GPU on our server, I’m unable to use the visualization interface for transient structures within Linux. This limitation prevents me from selecting parts or setting up calculations. Has anyone encountered this issue before?

Would it be advisable to set up my case in Windows and then only use Linux for computation? The problem is that my case set up in Windows doesn’t seem to open directly in Linux. Any suggestions or workarounds would be greatly appreciated.

Thank you in advance for your help!

Absolutely, I can help you with running CFX coupled transient structural analysis on Linux without a GPU.
Visualization on Linux for Transient Structures:
While the ANSYS visualization interface for transient structures might not be available on Linux without a GPU, you can still perform the calculations and post-processing using other methods:
* Command-line tools: ANSYS offers command-line utilities like CFX-pre and CFX-solve for setting up and running the simulation on Linux. These tools provide text-based interfaces for defining the problem and launching calculations.
* Scripting: You can leverage scripting languages like Python or Jython to automate tasks and interact with the solver through its API. This offers more flexibility for complex setups.
* Paraview: ParaView is an open-source visualization tool that can handle results from ANSYS simulations. You can export the data from your Linux simulations and post-process them in ParaView on any platform, including Linux without a GPU.
Case Setup and Transfer Between OS:
It's generally not recommended to directly transfer case files between Windows and Linux due to potential OS-specific settings. Here's a better approach:
* Set up the case in Linux: Utilize the command-line tools or scripting to define the geometry, mesh, material properties, and boundary conditions in your Linux environment.
* Solver and libraries: Ensure you have the appropriate ANSYS solver and libraries installed on your Linux system that match the version used for case setup.
By following these steps, you can establish your case entirely within Linux and avoid compatibility issues.
Additional Tips:
* ANSYS Documentation: Refer to the ANSYS CFX documentation for detailed instructions on using command-line tools and scripting for coupled fluid-structure interaction (FSI) simulations.
* Online Forums: ANSYS user forums and online communities are valuable resources for troubleshooting and finding workarounds related to CFX on Linux.
I hope this helps! Feel free to ask if you have any further questions.
